I have a '97 310 bought new in March '99 The boat has blisters. This is covered under warranty and Hunter has said they will cover this at the normal time for haul out and paint. Has anyone had experience with Hunter on this issue. Waine Ratliff

Hunter does what it says it will do. You didn't discribe the blisters or the location. Since the cause varies considerably from condensation during layup, air bubbles, to water getting into the laminate, it would help if you would describe the blisters in greter detail.

I Have just pulled my boat for the season and have found the the starboard side of the hull has a large number of dime size blisters. The port side seems to be ok. I keep the boat in a slip for about six months a year (from May through Nov.) The boat is a Hunter 26. I do not use the trailer for anything but winter storage. This is the first sign of blistering. I am the first owner and purchesed the boat in the spring of 97. Any comments would be appreciated. I have contacted the company but have had no reply so far. As might be expected I cannot use the boat until the blistering problem has been taken care of. Has anyone else had hull blistering problems and how common are they. I have had other boats and have used them in like conditions and have never had the problem

Donald: Blisters are not the end of the world. There are plenty of boats running around with blister. They will sail just fine with them. The end of the season is upon you so it is not a big deal that you would pull your boat and put it on the trailer anyway. Your boat is new enough that it 'should' be covered by Hunters 5 year warranty. Just call Hunter and see what they are going to do for you.

Take care of it asap

It is a good Idea if you are going to have the work done to do it as soon after pull-out as possible. Those blisters are pressure filled with an acid that will some times disappear back into the laminate over the winter and be missed if the work is done in the spring. The best thing to do is to pop them so that the blisters can all be located and dried out in the spring. ( Consult with the factory if they are going to repair the problem) Hope this helps. r.w.landau

For new boats , the best solution..

..is preventive epoxy barrier coated from anew. In our warm water , year around season , this is a standard procedure ,if done with high quality paints and procedure (next best thing is to have the boat out of the water for few months every year..). I did it on my 5 years old 29.5 , and so far no problems.. Re this application , after blisters tratment , there are mixed oppinions. The new thinking is that , epoxy coating a previously blistered ( by osmosis , no due to badly antifouling painting..), might stop the inner small amount of liquids that are still present 'under skin' , from slowly 'migrating' out thru the gelcoat and antifouling paint to surounding water and eassing on the problem in future;if epoxy covered , they don't show outside, but accumulate nevertheless inside and cause more actual (and deeper) damage ,if way out is bloked;next time , there will be more blistering , and especially more work to remove the thick and hard epoxy barrier coat; all this since the now beleif is that unless hull dried and HEATED (professionaly , under controled and forced procedure and enviroment) in the repair proccess ,( and even this doesn't always succeed) the 'seeds' of osmosis remain underskin , to reaper in few years in other places.. In this case local treatment of blisters only, and then antifouling , is the better solution (techical and financial..), to be redone probably every several years.. But in severe case of blistering , when hull strenght might be lessened , epoxy treatment (and some fiberglass aplication too ) is needed antway. Still the best thing would be more perfect GRP manufacture procedures , both in materials and especially quality controlled work and enviroment.
